OHL has won the EPC (Engineering, Procurement and Construction) Ski contract tendered by the Norwegian National Rail Administration, as part of the Follo Line transportation project, currently the country’s largest.

This contract, OHL’s first on this market, has an approximate value of 2.5 billion NOK (290 million euros). Pursuant to Norwegian public procurement laws, the contract will be signed in early August, following expiration of the mandatory claims period, and works will begin immediately after.

OHL has won over a total of five pre-selected companies. The client has designated OHL based on technical and economic criteria. As stated by the Follo Line project management, “the designated company meets our competitive price requirements as well as long-term experience. OHL has proven its capacity to undertake large projects in new markets. Its technical solutions meet all our requirements, as well as its highly experienced and qualified staff”.

Features of the project

The project site is approximately 25 km. south of Oslo and involves reconstructing the Ski railway station, extending it to include the high-speed line (Follo Line). In addition to these works, the station’s surroundings will be developed to include all railway facilities related to reconstruction of the former and new lines.

Specifically, EPC Ski covers a total section of 3.5 km and the worksite ranges from the south exit of the Follo Line tunnels to the south of the town of Ski. The work will cover activities to continue with the TBM Tunnel contract, once it opens to the outside (open section).

The scope of the work for this open area between Langhus and Ski will cover a seven-rail section, rearranging the two existing rails along the Osfold-Line, executing two new high-speed lines along the Follo Line and two connecting rails, and several constructions covering access roads, emergency lanes, sound barriers, tunnel portals, etc.

In the Ski area, the existing station will be totally reconstructed. The new one will include six rails, three central platforms with shelters and an underground pass. A road bridge will be built over the new rails, a new bus terminal, facilities for bicycle parking, extended parking for cars, new roads with sidewalks and new technical buildings.

The railway systems are part of the scope of work covering both the open section between Langhus and Ski, and the new Ski station.
